To @ZZ whom t may cm1/cern:

Re it lnov/n that l, MrLToN H. SnorinnERG'-, a citizen of the United States, esiding in the cityand county of San Francisco and State of California, have invented neuT and useful Improvements in Electrical Heaters, of which the following:r is a specification.

My invention relates to an electrical heating apparatus.

lt consists in the combination ot' heating elements with connecting terminals, and

their relation to the body to be heated.

lt also comprises details oi construction which will be more fully explained by rel l5 erence to the accompanfyring s Wings, in

Which- Figure l illustrates an clement. 3 its application to a laundry iron.

lt is the object of this invention to provide 2O an improved electrical heater. l' have in the present illustration shown such a heater in conjunction With a laundry iron.

represents the hollow base of such an iron, and B is a top or cover which may be secured Z5 upon the base by screws or in other convenient manner, and by in ,aus of handle C attached to the cover the 1'ron ina-r be properly manipulated. 'in order to h this n l employ a core Whic i n. up cl a pl' ality of plates 2 and 3. These plates such form as to tit the cavity in the ba l are separated iront each other by ad insel material, preferably thin sheets ci nu( r 7 similar insulatingrnaterial also fitted around the exterior of the plates, arnaked electrical conducting wires o are Wound tightly around the outside oi the plates and insulation, thus binding the vhole closely and iiriuly together, these Wi i sufli -O ciently separated from each other to prevent short-circuiting.

@ne end of the Wire conne with ont-1, end of one or" the ulates, and the opposize end is connected with the opposite end of the other platei ulatcs forming the cofre upon which the coil is made.

lllach of the plates has s connection as atfieg; tin upward or otherwise ronvcnicn 5C so that connection therewith may be one end of thc apparatu:`| uhm' poles are located.

tly disposed made at both those `This avoids the necessity oi a return wire to the roar end. of the iron or other body to be heated.

The core plates with their' terminals are preferably stamped or formed in a single piece, and the element is thus easily placed in the body to be heated orreinoved theretroni in case repairs or inspection should be necessary, Y

The structure thus formed is compressed into the container and heat will be ltransmitted from the structure to the container or body to be heated; the proportionate bull; of which serves to absorb the heat, and by reai sonA o the compression, the heat is easily' transmitted. T he bulk oi the exterior body to be heated serves to absorb any surplus heat, and thus prevent over-heating of the wires and consequent burning out ot the ln Figs. 2 andy 3 l have particularly shown means for regulating-the heat Where a plural-- ity oi plates 2-3-3a are employed.

l .have here shown three plates 2, 3, 3?, and three poles or plug connections 4, da, 5. li it is desired todispose the connections so as to provide for dil'erentdegrees of heat, one end of the Wire 6 is connected with the post 4E. From the opposite end oi the plate 2, the Wire is coiled about the plates aspre iously described, until it reaches the intermediate connection It Where the electrical current leaves the apparatus by means ei' a suitable plus; or connection as at 7, und thence throng-l the plate to 4'. By interrupting; this circuit and continuing the current through the wire to the end, and connect ingT with the pole 5, the Whole length ol the wire will be vincluded in the circuit and the resistance thus increased.

lt will be inanil'cst that by the intro duc tier of a number of such connections the heat inin parted may be varied and regulated.

llaving thus described niy invention, *what 'l claim and desire to secure by vLetters atent i" l. combination, with heated ol electrical heating; elements, said elements comprising plurality ol insulate'` coro plates having` integral teru'linals, insulatine means by which said plates are sepa rated. other insulation inrlosing the cores and electrically resistant wires Wound around said coros and connecting with the terminals.

'l'. lo on electric heater, a mechanism consistine' ol' a plurality oi coro platos insulated from nach other, said cores havingr terihinals formed integral with them et one end, insulating inateiiel inelosing said cores, en eleotrieztlly resistant naked Wii'e Wound around the exterior of said cores and insulation, with the Coils separated from eeel'i other and oonneetion between said Wire und the terminals sind core plates,

3. In an electrical beating apparatus, e plurality of 'flat core plates insulated` from eaoll other and having en inelosing insulating" film, an eleetrieally resistant naked Wire coiled about the Cores and tlieiil insulation so as to compress the parts together, the coils et seid Wire being seperated from each other, terminals formed integral Witlithe cores and at one end of the structure, the body te be heated having a, cavity Within which the heating mechanism is oompessed and Vthe parts maintained in close contact.

ln en eleetiie heater, e plurality of eoi'e plates insulated from. each other and hsvH ing independent integral terminals, a single Winding of naked Wire in separated coils insulated from the core plates and independent conneetions between said Wires en said plates whereby different lengths of Wire sind resistance may be introdueecl into the eiifeuit. In testiu'iony wlieieel l have hereunto set my band in presence of two subscribing witmesses.
